CSC panel mass production technology R&D plan for SSC GEM Detector Muon Subsystem
- and others
A Cathode Strip Chamber (CSC), in the SSC GEM Detector Muon Subsystem, uses honeycomb panels to precisely position the cathode readout strips that define the volume of each detector layer. These panels also support and accurately position the anode wires within each detector layer. The largest panels are approximately 1.5 meters by 3.5 meters and 20 mm thick. The panel cross-section is illustrated in Figure 1. Each panel must remain flat to 100 microns over 1.5 meters, to meet physics objectives, while serving as a key structural component of the chamber assembly. The GEM Detector uses 1,128 CSC`s (``24/36/48`` configuration) requiring a total production of approximately 10,000 precision panels (8,088 plus spares). Mass production techniques are required which can produce the large number of panels for minimal cost and within a reasonable schedule while maintaining structural and stringent physics requirements. The goal of this R&D effort is to define, develop, and verify appropriate technologies that can be fashioned into an overall fabrication process for mass production of CSC panels. In addition, panel design features are evaluated which aid in CSC assembly and internal alignment.
